Karacoline

Revisión del cliente

Based on 1 Customer Validation

Karacoline is an orally active PPARγ activator and ERK/JNK MAPK inhibitor. Karacoline restricts ROS production, maintains mitochondrial membrane potential, and inhibits pulmonary cell apoptosis. Karacoline inhibits NF-κB pathway activation, reduces acetylation levels of p65 and the expression of MMP14 and MMP9, enhances the expression of type II collagen (collagen II) and aggrecan (aggrecan), and suppresses extracellular matrix degradation. In a mouse model of sepsis-induced acute lung injury, Karacoline alleviates lung injury, inhibits the release of IL-1β, IL-6 and TNF-α, increases the Bcl-2/BAX ratio, and reduces caspase 3 expression. Karacoline can be used in research related to acute lung injury and intervertebral disc degeneration.

Karacoline (1.6 μM; 24 h) upregulates the expression of PPARγ in LPS-stimulated MH-S cells, inhibits the JNK/ERK MAPK signaling pathway (excluding p38), and simultaneously suppresses the expression of MMP9^[1].
Karacoline (0.001-1000.0 μM; 24 h) has an IC₅₀ of 6.444 μM in primary rat nucleus pulposus cells, and Karacoline (1.25 μM; 0-3 days) partially reverses TNF-α-induced cytotoxicity in these cells^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
